Cut the cauliflower into florets and boil in salted water. Roughly chop the cooked cauliflower.

While the pasta cooks, sauté garlic in a skillet with olive oil, then add the cauliflower, a pinch of red pepper flakes, and salt to taste. Add a little pasta cooking water if needed.

Drain the pasta and toss it in the skillet with the cauliflower. Add grated Parmesan cheese to taste.
